A Spokane, Washington woman, out for a hike with friends two weekends ago, says she may have captured video of the mythical Bigfoot, the elusive man-ape hybrid who walks upright, has excessive body hair, and seems impervious to in-focus photography.

As reported by KXLY TV in Spokane, the young woman, identified only as "Samantha," was shooting video in a wooded area near the Spokane River when a tall, shadowy humanoid (with seemingly bad posture) was caught on film. Because the creature was some distance away, she didn’t notice it at the time.

But when Samantha got home and watched the video, she spotted the mysterious stranger moving left-to-right through the frame, the report says. A few days later, she posted the clip on YouTube. The video has since gone viral with more than 579,000 views as of the afternoon of May 30.
